Future WAAS Procedures
• LPV 200’ Minimum
– Minimum decision height of LPV approach lowered from 250’ to 200’
– First approach was published in 2006
• LP Approach
– Acts like a Localizer approach utilizing WAAS horizontal protection limits (HPL)
– Criteria being developed, estimated to be complete within 6 months
– Can be developed at approaches that fail to meet LPV criteria due to obstacle penetrations 多谢多谢，支持支持 学习学习这个
